SPINNING 0R TVYIETING RING.

Application filed June 18,

My invention relates to rings for spinning and twisting frames, andparticularly to rings ot' the type purposed to carry horizoutal. ratherthan 'ertical travelers; that is to say, rings flanged at their tops topresent a general I or T shap in transverse section.

The essential. objects of my invention are to lubricate both the web andthe lhuige or Hinges of the ring; to prevent both excoriation of theweb, and wear or friction oil the horns oi the traveler; and to effectthese ends in. such a manner as to avoid any obseruction to the horns ofthe traveler in its MOW? went over the ring.

To the above ends essentially my inveiiin such parts, and in suchcomlion COHSiQLS binatious of parts, as fall within the scope of the.ppended claims.

In the accompau drawings which form. a part of this spec tion,

l gure l a plan view of a r for spinniitig' and twisting frames embed myV-'1'i0ll together with a traveler oi the ontal type mounted thereon,

:iu=e 2, a section 0f ring),- taken on line of I ire 1, and

' similar section of a inodilicd Iuce numerals indicate like partsthroughout the views.

As herein shown the wel.) portion 5 of my ring provided new its lowerend with an external annulz-ir sl er 6 to form an abutine t for thering); rail, but this ehouhiler may be mnitted if desired, and th hapeoi the vertical web in cross section inunalerial. The web is integral atits top with the n line of the flange 7. This flange comp es fiatcentral portion 8, and flat laterally extendii'ig; of wing, portions 9all in the same horizontal plane. Interior, annular, transverselyswelled or curved shoulders 11 form traveler bearings.

In. the top of the central portion 8 of the flange is an annularchannel. 13, of truucoconical cross section in this instance, from thebottom portion of which at intervals we tend downwardly inclinedpassages 14:, each terminating at the junction of the web with ashoulder 11. The passa 'es are directed successively to opposite sidesof the web.

1928. semi No. 28mm.

The traveler 18 for which this ring; is purposed is of the horizontal orhow typo comprising); the arched or sen!icyliudrical. body 19 and flathorizontal. horns 20. The portion 19 does not in o g icration contactwith the flange, but the bearing is substantially, on the horns 20, uponthe shoulders 11, and incidentally upon the web 5.

In Figure 3 is shown a ring of the same characti-n' as that in Figures 1and 2, but of the reversible type. In. this alternative embodiment of myinvention the second flange 22 is identical with the flange 7, and isprovided with the channel 13 andpassages 14c already described.

In employing my ring; a liquid lubricant, either independently or in asaturated material, is placed in the channel 13 and exudes through thepassages 14. The location of the d barge era .5 of the pa s such that l.e emergiu liquid not onl lubricates the vertical fa oi the web whiche2- p used by the extremities of the traveler horns 20; but; also flowsdmvnwardlyf and out vardly over the shoulders 11, thus luljiricating thelatter and preventing l lotion and wear upon the coi'itacting l; 11gsurfaces of the horns. i

The direction (at the lubrieating passages to both sides of the ringprotects the b from exc tri ional coutaet rcgaiu ess of which horn isengaged therewith. The shoulde s 11 fi'lrlher eliminates .t'r ion bypresenting minimum. contacting areas to the horns. A further importantfunction of the shoulders is to keep the horn extremities remote ilinomthe pa or openings 14 which would otherwise, in certain tilted positionsof the traveler, catch and impede the later in its annular travel.

I clain1:-

1. In a spinning or twisting ring of the character described, a web, aflange centrally integral with the web and provided with an annularchannel in its top in the vertical plane of the web, and with pas agesextending from the channel to points adjacent the web at opposite sidesof the web.

2. In a spinning 0r twisting ring of the character described, a web, aflange integral with the web provided with an annular channel in itstop, a transversely curved shoulder upon the bottom of the flange, saidflange being also provided with a passage extending from the channel tothe bottom of the flange.

In a spinning or twisting ring of the character described, a web, ahorizontal fiange' centrally integral with the web provided centrallyWith an annular channel in its top portion and with downwardly inclinedpassages extending from the channel to the bottom of the flange adjacentto the web, and bearing means upon the bottom of the flange for spacingtraveler horns from the passages.

4. Ina spinning or twisting ring of the character described, a web, aflat flange comprising a central portion integral with the top andlaterally extending wing portions, and depending shoulders upon the wingportions extending from their ends to points adjacent the web, saidcentral portion being provided with an annular channel, and with spacedinclined passages extending in succession from the channel to pointsintermediate the web and shoulders at opposite sides of the web.

In testimony whereof I have affixed my signature.
